The following describes in detail the use steps of a smart partitionfence that can automatically prevent pedestrians from overturning inconjunction with FIGS. 1 to 3 below:

At the beginning, the slider 20 is in the upper limit position, and thefirst spring 23 is always in a compressed state. The electric wire 24 isin an interrupted state, and the pushing block 30 and the fixing plate31 are in an upper limit position.

When someone tries to climb over the guardrail, if they rest on thefixed plate 31 with their hands or feet, the fixed plate 31 and the pushblock 30 are pushed down, and then the pressure sensor 32 is presseddown by the second spring 33, and the pressure sensor feels the pressurechange. 32 Start the first motor 37 on the same side, and then the firstmotor 37 inflates the elastic airbag 28 on the same side, so that theelastic airbag 28 is inflated to a semi-saturated state. The end of theelastic airbag 28 that is far from the center of symmetry protrudes tothe outside to try to overturn The person cannot continue to be close tothe guardrail, but when the person steps on the borrowing force, becausethe elastic airbag 28 is in a semi-saturated inflation state, theelastic airbag 28 will sag so that the pedestrian cannot be surpassed bythe force. When the fixed plate 31 is no longer under pressure, thepressure sensor 32 The first motor 37 on the same side is started toreverse, and the air in the elastic bladder 28 is drawn back into thegas storage cavity 34. The elastic bladder 28 is stored in the storagecavity 27 under the elasticity of its own material.

If you grasp the rocker 13 or the fixed block 16 and continue to try toclimb over the guardrail, when the rocker 13 and the fixed block 16 arestressed, due to the action of the connecting rod 18 and the limit rod15, the rocker 13 and the fixed block 16 shake and slide down and passThe turntable 22 drives the slider 20 to slide down. When the slider 20slides to the lower limit position, the conductive block 26 is insertedinto the slot 25 and the electric wire 24 is connected, and the secondmotor 43 is started. At this time, the first gear 40 follows the slider.20 slides to the lower limit position and meshes with the second gear47, the second motor 43 starts to drive the first helical gear 44 torotate, and then the gear shaft 45 is rotated through the gear meshing,and then the gear shaft 45 drives the second gear 47 to rotate, thesecond The gear 47 rotates the rotating shaft 21 through the gearmeshing, and then the turntable 22 rotates and drives the connecting rod18 to rotate. The connecting rod 18 drives the lower end of the rocker13 to flip, so that the upper ends of the rocker 13 and the fixing block16 are constantly shaken and cannot be overturned by force. To preventpedestrians from jumping over, when there is no pressure interferencebetween the rocker 13 and the fixed block 16, the slider 20 slides upunder the action of the first spring 23, the conductive block 26 leavesthe slot 25, and then the electric wire 24 is disconnected, and then Thesecond motor 43 stops operating Return to the initial state.

The beneficial effect of the present invention is that the presentinvention can effectively separate the flow of people or traffic, andautomatically start when a pedestrian tries to climb over the guardrail,so that the pedestrian can't climb the borrowing force in a gentleoperation manner, thereby preventing Pedestrians crossing fences causetraffic jams or even traffic safety accidents, improving the safety oftraffic roads, and automatically stopping when no one is crossing,saving environmental protection.
